How To Add Fractions Using Grids

in which quadrant is the pointnegative 7 comma 7 located? so let's just reviewwhat a quadrant is. a quadrant are eachof the four sections of the coordinate plane. and when we talkabout the sections,

How To Add Fractions Using Grids, we're talking about the sectionsas divided by the coordinate axes. so this right here is thex-axis and this up-down axis is the y-axis.

and you can see itdivides a coordinate plane into four sections. we call each of thesesections quadrants. this one over here, where boththe x-values and the y-values are positive, we callthe first quadrant. and we use the roman numeral i. then if we kind ofmove counterclockwise around the coordinateplane, this quadrant where the x-values are negative andthe y-values are positive,

we call this thesecond quadrant. i could write it. we call this thesecond quadrant. then we go down here whereboth the x-values are negative and the y-values are negative. we call this the thirdquadrant, once again using roman numerals. then finally the quadrantwhere the x-values are positive but the y-valuesare negative, we

call this the fourth quadrant. so let's see which quadrantthe point negative 7 comma 7 is located. so there's two waysto think about it. you could just say, look,we have a negative x-value. our x-value isnegative, so we're going to move to the left. so we're going tobe on this side. we're going to be onthis side right here

just by the fact thatthe x-value is negative, we're going to be either in thesecond or the third quadrant. now, we know that they-value is positive. we know that they-value is positive. so if the x-value is negativeand the y-value is positive, we're going to landsomeplace right over here in the second quadrant. the other way tothink about it is you could literallyjust plot this point

and see that it fallsin the second quadrant. so let's do that. if x is negative 7. so that's negative 1, negative2, negative 3, negative 4, negative 5, negative6, negative 7. did i do that right? 1, 2, 3 4, 5, 6, 7. so this is x is negative 7. and then we have togo up 7 because y

is equal to positive 7. so 1, 2, 3, 4, 5, 6 7. so the point negative 7comma 7 is right over here, clearly lies in thesecond quadrant.
